Comments
CSL supports three different forms for comments. A comment that spans lines can be enclosed between /* and */, while a single line comment can follow either a double-slash // or a pound sign #.
You can add or remove the // prefix for multiple lines at once, by doing the following:
1 Indicate the lines to comment or uncomment by selecting at least some text from each line.
2 Select Toggle Comment from the Edit menu, or type Ctrl+K. Alternatively, in some locales, you can type Ctrl+/ (that is, hold down the Ctrl key and press the forward slash).
If the first selected line is commented, this uncomments all selected lines. If the first selected line is not commented, this comments all selected lines.
